It will gently correct the vehicle back into the center of the lane on equipped models. If the driver engages the steering wheel, the correction will be overridden, and the driver then has full control of the vehicle. Lane indicators (solid and dotted lines) must be clearly visible for this system to engage.


Toyota Pre-Collision Braking IndicatorPre-Collision Braking 

This warning light indicates the Pre-Collision Braking (PCB) has required the automatic emergency braking system (AEB) to be engaged. The system has detected a possible collision from a vehicle in front that is approaching too quickly. The automatic emergency braking system will automatically take over, decelerate, and brake the vehicle to give the driver time to react and prevent a collision. It is part of the Toyota Safety Sense (TSS) system.


Toyota Park Assist IndicatorPark Assist 

The park assists indicator means the system is active and functioning. If it is enabled while parking, the vehicle will assist the driver in steering when trying to park the vehicle in forward or reverse. It utilizes the car’s multiple cameras and sonar. It will apply the brakes if it detects a collision.


Toyota Intelligent Clearance Sonar OFF IndicatorIntelligent Clearance Sonar OFF

Toyota Rear Differential Lock IndicatorRear Differential Lock 

This rear differential lock indicator means that the rear differential has been electronically locked to provide more traction to the rear wheels. The light will come when the vehicle is stuck and one of the rear wheels is spinning independently of the other. For the light to go off, the vehicle may need to be unstuck or the differential serviced as it may be malfunction.


Toyota Automatic Limited Slip Differential (LSD) IndicatorAutomatic Limited Slip Differential (LSD) 

The automatically limited-slip differential indicator means that power is being sent to the wheel, getting traction on the road, and a brake is applied to the wheel where slip occurs. It can only be used with traction control off as it sends more power to the wheels without reducing engine speed or braking. It is not to be used in extreme weather conditions while moving in place of traction control. It is used when accelerating from a standstill in slippery conditions to help get power and traction to the road without losing engine speed. The auto limited-slip differential indicator will go off when the traction control system is turned on.


Toyota Low Speed And Crawl Control IndicatorsLow Speed and Crawl Control

It also avoids getting stuck or slipping on slippery or difficult terrain. This light will be on when this mode is active. This mode can be turned off completely by pushing the button on the dash, and the light will also turn off.


Toyota Turn Assist IndicatorTurn Assist 

The turn assist indicator means the vehicle assists in cornering performance. It controls steering and maintains vehicle speed when driving through a tight corner. Effectively, it reduces the number of turns needed to navigate a corner that requires turning the wheel in the opposite direction. It only works in conjunction with crawl control being turned on. To turn this light off, turn the crawl control off.


Toyota Auto Glide Control IndicatorAuto Glide Control 

The auto glide control (AGC) is a fuel-saving technology equipped on some Toyotas to let a vehicle coast without aggressive engine braking. When the AGC is active, it acts as a drive setting allowing the vehicle to go into a neutral gear that limits vehicle speed loss. This happens because less deceleration torque is applied to the transmission from the engine losing acceleration. The indicator light comes on when the AGC engages to alert the driver of loss of speed while coasting. The ECO mode must also be turned on for the AGC to be active.


Toyota Economy Operation IndicatorElectronically Controlled Transmission Power Mode 

The electronically controlled transmission (ECT) power mode is a Toyota driving mode equivalent to tow/haul mode on most other makes.

This indicator can be turned off by pressing the ECO MODE button on the dash, returning the car to normal function.


Toyota Sport Mode IndicatorSport Mode 

The sport mode indicator means that the sport mode is active. Sport mode automatically makes adjustments to the transmission, throttle, and steering for a sportier feel. Shifting is quicker,  acceleration is quicker, and steering is more responsive. To turn the light off and return the car to normal driving mode, push the sport mode button or normal button on the dash. 


Toyota EV Mode IndicatorEV Mode 

The EV mode means the hybrid vehicle runs on battery power, and the gas-powered engine is turned off. This indicator means the hybrid vehicle is working properly. This light will remain when the vehicle is still using battery power and goes off when the electric motor or gas engine turns on.


Toyota Hybrid Ready IndicatorHybrid Ready 

The ready indicator light on a hybrid vehicle means that the electric systems checks have passed, and the vehicle functions normally. It is ready for use, aka driving. It will go away when the vehicle moves after the initial start-up and stay off until the vehicle is turned off.


Toyota EV Operation IndicatorEV Operation 

The EV operation indicator means the hybrid vehicle is using battery power to function. When this light goes off, the electric motor likely needs to kick on to provide enough acceleration when pressing on the throttle.


Toyota Remote Charge Timer Setting IndicatorRemote Charge Timer Setting 

The remote charge timer indicator shows a time set for a hybrid vehicle to be charged. This time can be set with the owner’s preference in mind. While it’s plugged in and this timer is set, the vehicle will charge at the set time. 


Toyota Cruise Control IndicatorCruise Control  

This light means that cruise control has been enabled and is functioning properly. Once a switch or lever sets the cruise control speed, the vehicle will keep constant speed until the brake pedal is pressed. Once the brake pedal is pressed, the cruise control will cancel. The cruise control can be deactivated by the switch/lever, and the indicator will no longer show.


Toyota Dynamic Radar Cruise Control IndicatorDynamic Radar Cruise Control 

This light means that adaptive cruise control (ACC) has been activated. The vehicle will keep a safe distance from the vehicle in front. If the vehicle in front slows down, your vehicle will slow down as well. If a possible collision is detected, then moderate to heavy braking will be applied, an audible alert will chime, and a visible warning will show on the information display.


Toyota Adaptive Front Lighting OFF IndicatorAdaptive Front Lighting OFF

Toyota Headlamp IndicatorHeadlamp 

The headlamp indicator means the normal headlamps are active. This indicator will go off when the vehicle’s headlights are turned off.


Toyota LED Headlamp Out IndicatorLED Headlamp Out 

The LED headlamp out indicator means one of the headlamps has gone out by either a bad LED bulb, blown fuse, or faulty wiring. A message may appear on the dash alerting the driver to the location of the position where the fault is occurring. To get this indicator off, the vehicle must be serviced so the headlamp is functioning again.


Toyota Headlamp Leveler  Fault IndicatorHeadlamp Leveler Fault 

The headlamp leveler fault indicator means that one of the leveling system’s parts is not functioning as it should, such as the leveling sensors in the front or rear of the motors that actuate the headlamp movement. This can also happen when a vehicle is lowered and the system maxes out its ability to level the headlight upwards. The vehicle must be serviced to remove this indicator from the dash.


Toyota Automatic High Beam IndicatorAutomatic High Beam 

This light means that the high beams will turn on automatically when there is no incoming traffic. The automatic high beam switch needs to be on, and the high beams are turned on for the automatic high beams to work.


Toyota Park Lamps ON IndicatorPark Lamps ON 

The park lamps indicator shows that the parking lamps are running. Parking lamps were originally intended as a dim light to be left on while the vehicle was parked in situations where there wasn’t much street light. However, that doesn’t apply in modern situations, and no one uses it in that way anymore. The best use of these lamps, and probably the only way they are used today, is in situations where it is not quite dark enough for the headlamps to be on. The parking lamps would help give the vehicle visibility, like the headlights, without being too bright and distracting. 


Toyota Fog Lamp IndicatorFog Lamp 

This light means that the fog lights are turned on. Some vehicles are also equipped with rear fog lights, and an illuminated symbol that is red or amber and pointing to the right will usually indicate the rear fog lights are on.


Toyota Turn Signal IndicatorTurn Signal 

The turn signal indicator should flash when the stalk is switched on in either direction. If the light blinks fast, it is an indicator of a bad turn signal bulb. If the light stays on steady when the turn signal stalk is switched on, it indicates a bad stalk/switch. Have a Toyota technician replace the bad bulbs or faulty switch.

Common turn signal indicator problems on a Toyota vehicle:

  • The turn signal switch is faulty. 
  • Burnt out/ bad turn signal bulb
